California Freethought Day 2025
California State Capitol Building, 1305 10th Street, Sacramento, CA, USCalifornia Freethought Day combines the fun and atmosphere of a fair with the education and activism of a conference. It's a festival of freethought.
Our theme this year is “One Nation, Indivisible: Liberty and Justice for All” as we explore the current administration’s growing attack on marginalized communities and the rise of Christian Nationalism.
Join us at our free event to celebrate freedom of speech and thought, civic engagement, enthusiasm for science, social justice, and the separation of church and state.
Our event will be outdoors at the California State Capitol Building and livestreamed via Facebook, YouTube, and X.
